Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...

For more than 50 years, scientists have theorized that a special kind of reflection known as time reflections have existed in the realm of quantum mechanics. However, proving the existence of this ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a ...

NEW YORK, March 13, 2023 — When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored ...

THE principle that a regularly stratified medium selectively reflects a monochromatic beam of radiation incident on it at the appropriate angle is well known and forms the basis for the X-ray analysis ...

DURHAM, N.C. -- Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The ...
